武汉区域碳排放时空规律及应对策略研究
Spatio-Temporal Pattern of Carbon Emissions and Response Strategies in Wuhan Region
詹庆明 赵欣悦 唐路嘉 李轩 ‖ Zhan Qingming, Zhao Xinyue, Tang Lujia, Li Xuan
碳排放增加所导致的全球气候变化深刻影响着人类生存和发展，已成为当今人类社会可持续发展面临的严峻挑战。本文聚焦于武汉所在的多层级区域，即湖北省、武汉城市圈和武汉市三个不同空间层级，探讨分析各区域的碳排放和碳汇时空分布特征与差异。并在武汉市层面进一步细化空间粒度，从而揭示城市内部碳排放和碳汇的空间关联性及差异性。在此基础上，本文分别针对省域、城市圈和市域三个层级提出相应的减碳增汇的策略和建议，以此为区域可持续发展和低碳生态城市建设提供支撑。
Global climate change, driven by increasing carbon emissions, has posed a significant challenge to both human survival and development, becoming a major issue for the sustainable progress of human society. This paper examines the characteristics and differences in the spatio-temporal distribution of carbon emissions and sinks across Wuhan Region that is stratified into three spatial levels: Hubei Province, the Wuhan Metropolitan Area, and Wuhan City. On a finer spatial scale within Wuhan, it uncovers the spatial correlations and disparities between carbon emissions and sinks. Accordingly, the paper proposes strategies and suggestions for reducing carbon emissions and enhancing carbon sinks at the provincial, metropolitan, and municipal levels. These findings are valuable for sustainable regional development and construction of low-carbon eco-cities.
